' v'TOOL HANDLE.

Application filed October 4, 1922. Serial No. 592,275.

To all whom t may concern:

Be it known that I, FRANK ZYGMUNT, citizen of the United States,residing at Plantsville, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements in ToolI-Iandles, of which the following is a specification.

rIhis invention relates generally to mechanics tools, having moreparticular reference to a tool designed for heavy work, the inventionrelating to the construction of the handles and having for an object theprovision of handle adapted to stand unusual strains, a furtherdevelopment of the invention relating to the utilizing of the handle asa hammer.

For further comprehension of the invention, and of the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawings, and to the appended claims in which thevarious novel features of the invention are more particularly set forth.

Fig. l of the drawings is a side view showing my invention applied to ascrew driver.

Fig. 2 is a transverse sectional View taken on the line 2 2 of Fig. l.

Fig. 3 is a central longitudinal sectional view taken at right angles toFig. l.

Fig. 4 is a transverse sectional view taken on the line 4 4 of Fig. 3.

In the construction shown in the drawings I have illustrated myinvention applied to a screw driver comprising a shank l flattened atits end, to engage the slots in the heads of the screws. This shank l0is rigidly united with the metallic element of the handle of the screwdriver. The shank l() extends freely through the main barrellike body 2Oof the handle and is rigidly connected to the solid outer end portion 20of the latter. The body 20 of the handleis formed with a number ofradial ribs 12. In the spaces between the said ribs are set woodeniiller blocks l which are secured in place by suitable pins, theseblocks being formed to give a circular cross sectional form to thehandle, as shown in Fig. 2.

The recess 21 in the handle which accommodates the shank is of greaterdiameter than the latter and in the space thus left is a sleeve 22 whichts snugly on the shank. This sleeve 22 is exteriorly screw threadedadjacent each end as shown at 23, while the recess 2l in the handle hascomplementary interior screw threads 24 at its lower end.

The end element of the handle is formed with a transverse aperture 2G inwhich is received a hammer head 27 which occupies the position shown inFig. 3, lying within the contines of the part 20', or is projectedoutwardly to the position shown in Fig. 4 when the device is to be usedas a hammer.

To form a solid abutment for the hammer head, when in the position shownin Fig. 4, it is provided on its rear end with integral arcuate lugs 30which engage in recesses 31 projected laterally from the aperture 26,the top and bottom walls of the aperture being grooved as at 32accommodate these lugs 30 when the hammer head 27 occupies the positionshown in Fig. 3. As will be understood, the grooves 32 arecircumferentially odset from the recesses 31, a quarter turn of thehammer 27 moving it from position with the lugs 30 registering with thegrooves 32 to position with the lugs engaged in the recesses 3l.

To lock the hammer head 27 against rctation I provide a screw 25threaded into the end element and adapted to engage in either one of apair of sockets 36 in the hammer head. When the device is to be used asa hammer the hammer head 27 is projected to the position shown in Fig.4, the sleeve 22 is pulled outwardly, and the top threads 23 thereofengaged with the interior threads 24 of the handle. The sleeve 22 mayhave an enlargement 22 on its lower end to facilitate gripping thereof.

Having thus described my invention what I claim as new and desire toprotect by Letters Patent of the United States is as follows l. A toolof the type specified comprising an elongated handle, a hammer headslidable in one end of said handle transversely to the latter, saidhammer head being adapted to be confined entirely within the handle whennot in use and to be projected partially from the handle for use, andintegral lugs on said hammer head adapted to engage abutment shoulderson said handle to hold the hammer head projected.

2. A tool of the type specified comprising an elongated handle, a hammerhead of circular cross section slidable in one end of said handletransversely to the latter, said hammer head having a pair of lugsprojecting from opposite sides thereof, said lugs being adapted toengage behind shoulders in the handle to hold the hammer head partiallyprojected from the latter for use, said lugs being adapted to bereleased from said shoulders, to permit of the hammer head beingWithdrawn entirely Within lthe handle, by a partial turning movement ofthe hammer head.

3. A tool of the type specified comprising an elongated handle, a hammerhead of circular cross section slidable in one vend of said handletransversely to the latter, said hammer head having a pair of lugsprojecting from opposite sides thereof, said lugs being adapted toengage behind shoulders in the handle to hold the hammer head parsaidshoulders, to permit of the hammer head being withdrawn entirely Withinthe handle, by a partial turning movement of the hammer head, saidhammer head being formed With a pair of sockets spaced therealong, and ascrew in said handle adapted to engage n either of said sockets torespectively hold the hammer head against turning Vmovement `Whenprojected for use, or against outward sliding movement When not in use.

In' testimony whereof I have aliixed my signature;v

FRANK ZYGMUNT.
